Specification of Letters Patent.

Patented Jan. 19, 1909.

Application filed January 28, 1908. Serial No. 413,038.

To allfuiho'm it may concern: v

Be it known that I, Max Lrsonnn, a citizen of Germany, residing at Dusseldorf,

Germany, have invented new and useful Improvements 1n Machines for Leveling a Plastic Covering on Floors, of wlnch the following is a specification.

A mode of applying plastic compositions,

" such as plaster paris coverings, cork coveradvantage of precluding a further layer be- :ing put down until the last applied is dry,

in order not to mark it, whereby much time is lost. There is also the further .disad vantage that the covering which is newly laid on, does not unite to form an even surface with the already hardened part, but forms squares or stripes over the floor. These serious disadvantages are avoided by the present invention, by the wheels carrying 5 the frame being fixed at one side of the rollers, so that the tails are laid'beside the freshly covered strip. In this manner the Work can be carried out expeditiously and the fresh covering of each strip unites with the last one to form a perfect surface.

The accompanying drawing shows the device in Figure 1 a side elevation, in Fig. 2 a ground plan and in Fig. 3 a rear elevation.

As shown by the drawing, 2 U-iron rail 2' serve to guide the wheels, but other rails or straight pieces of wood may be employed. The Wheels or casters 9" of the frame are on one side of the roller a. The frame, or carriage as illustrated, is provided with three -wheels, but four can be used if desired. As the frame runs on two rails and is supported this fourteenth day of by the wheels, it cannot, so long as the wheels keep the rails, deviate from its course. a scraper I), which is so fixed that it takes oil the excess material laid on the floor and fills in thel'iollows with it. The scraper, then, in the first place, gives a smooth surface. to the com 'aosition &c., which is then rolled out to an equal layer and pressed together by the roller. The scraper b is adjustably fixed in the arms 0, so that it can he set exactly to the thickness desired to lie on the floor. In order to facilitate the adjustment of the scraper, it is provided with 2 slots (Z through which pass the securing bolts, but the adjustment may be effected in any other suitable and convenient manner.

The device is further provided with The roller, as well as the scraper, can be raised and lowered. The bearings L of the roller can be set by the screws 8.

I claim: v 1. A device of the character described, comprising a track, a carriage movable thereon, a roller, and means on the carriage for supporting-the roller on one side of the track, substantially as specified.

2. A device of the character described, comprising a track, a carriage movable thereon and having a bearing at one side of the track, and a roller journaled in said carriage and bearing, substantially as specified.-

3. A device of the character described, comprising a track, a carriage movable thereon, a roller, a scraper, and means on the carriage for supporting said roller and scraper on one side of the track, substantially as specified, I
